the HS-65MG are relatively small, fast, and strong. They handle crashes with far less stripped gears or other breaks than their plastic-geared brethren. They are a little more expensive, but they make up for that in durability and worry-free use.

In my opinion, this is the best servo for this size range. I have about 15 of these servos I use on all my 40-47" planes and haven't had one go bad yet. They have great response, speed and torque and the metal gears are impossible to strip. A great servo.
